1. NBR roj hmab nitrile
Lub solenoid valve yog tsim los ntawm emulsion polymerization ntawm butadiene thiab acrylonitrile. Roj hmab Nitrile feem ntau yog tsim los ntawm qhov kub thiab txias emulsion polymerization. Nws muaj cov roj ua haujlwm zoo, ua haujlwm hnyav, tiv tshav kub zoo, thiab muaj zog nplaum. Nws qhov tsis zoo yog qhov tsis kub tsis kam tiv taus, tsis zoo ozone tsis kam, cov khoom siv hluav taws xob tsis zoo, thiab qis qis dua. Lub hom phiaj tseem ceeb ntawm solenoid valve: solenoid valve nitrile rubber feem ntau yog siv los ua cov khoom tiv taus roj. Solenoid li qub xws li cov kav dej tsis kam, cov kab xev, cov roj hmab diaphragms thiab cov hnab roj loj tau siv los ua ntau yam khoom tiv taus roj, xws li O-rings, roj foob, thiab tawv. Cov tais, diaphragms, li qub, lub tog raj kheej, thiab lwm yam kuj tseem siv los ua cov ntawv roj hmab thiab cov khoom tiv taus
2. EPDM EPDM (Ethylene-Propylene-Diene Monomer) solenoid valve Lub ntsiab feature ntawm EPDM yog nws superior tiv thaiv oxidation, ozone thiab corrosion. Txij li thaum EPDM belongs rau tsev neeg polyolefin, nws muaj vulcanization zoo heev. Ntawm tag nrho cov roj hmab, EPDM muaj qhov qis tshaj qhov tshwj xeeb. Lub solenoid valve tuaj yeem nqus tau ntau ntawm cov muab tub lim thiab roj yam tsis muaj kev cuam tshuam rau nws cov yam ntxwv. Yog li ntawd, cov khoom siv roj hmab uas tsis muaj nqi tuaj yeem tsim tau. Solenoid valve molecular qauv thiab cov yam ntxwv: EPDM yog terpolymer ntawm ethylene, propylene thiab non-conjugated diene. Diolefins muaj cov qauv tshwj xeeb. Tsuas yog ib qho ntawm ob daim ntawv cog lus ntawm lub solenoid valve tuaj yeem ua tau copolymerized, thiab ob daim ntawv cog lus unsaturated feem ntau yog siv los ua kev sib txuas. Lwm qhov tsis txaus ntseeg yuav tsis dhau los ua cov saw hlau tseem ceeb, tab sis tsuas yog yuav dhau los ua cov saw hlau sab. Lub ntsiab polymer saw ntawm EPDM yog tag nrho saturated. Qhov no feature ntawm solenoid valve ua rau EPDM resistant rau tshav kub, lub teeb, oxygen, tshwj xeeb tshaj yog ozone. EPDM yog qhov tseem ceeb uas tsis yog-polar, muaj kev tiv thaiv rau polar daws thiab tshuaj, muaj dej nqus dej tsawg, thiab muaj cov khoom zoo rwb thaiv tsev. Cov yam ntxwv ntawm solenoid valve: â '" tsis tshua muaj siab thiab siab filling; â' ¡ aging kuj; â'¢ corrosion kuj; â'£ dej vapor kuj; â'¤ superheated dej tsis kam; â'¥ kev ua haujlwm hluav taws xob; â'¦ elasticity; § adhesion.
3. VITON Fluorine Roj Hmab (FKM)
Cov tshuaj fluorine-muaj cov roj hmab hauv cov solenoid valve molecule muaj ntau hom nyob ntawm cov ntsiab lus fluorine, uas yog, cov qauv monomer; cov roj hmab fluorine ntawm solenoid valve hexafluoride series zoo dua li silicone roj hmab hauv qhov kub tsis kam, tshuaj lom neeg ua haujlwm, thiab solenoid valve tiv taus cov roj feem ntau thiab cov kuab tshuaj (tshwj tsis yog ketones thiab esters), huab cua tiv taus, ozone tsis kam yog qhov zoo, tab sis txias tsis kam yog tsis zoo; solenoid li qub feem ntau siv dav hauv tsheb, maus taus, B thiab lwm yam khoom lag luam, thiab ntsaws ruaj ruaj hauv cov nroj tsuag tshuaj. Qhov ntsuas kub ua haujlwm yog -20 ° C. ～260â „ƒ, hom kub-tiv taus tuaj yeem siv tau thaum siv qhov ntsuas kub tsawg, uas tuaj yeem siv rau -40â„ ƒ, tab sis tus nqi siab dua.
